The invention relates to improvements in saw setsand an object of the invention is to ."provide a saw set which with reasonable care c'an'be used by the average individual to e'flFectively set the teeth of any saw whether large or small. I v A further object is toprovide a tool which when once set for a particular saw to be sharpened will give all the teeth the same pitc'h or set.

A further object is to provide a tool whlch can be easily and accurately set to give a greater or less pitch of the tooth and which is arranged such that the work is done by the squeezing together of the tool handles provided. I i A further object is to construct the tool in a simple, durable and inexpensive manner and so that the various partscan be readily 0 assembled or dismounted and such that the various settings can-be easilymade.

With the abovemore important objects 1n View, the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described, reference being had to the accompanying drawing, in which L Fig. 1 is a side View of the tool.

Fig. 2 is a plan view thereof,

tional view at 33 Figure2. I j p Fig. 4 is a perspective view of the frame of the tool.

' Fig. 5 is a face view of the adjustable-block. Fig. 6 is a plan viewv of the cam.

In the drawing like characters of reference indicate corresponding parts in the several figures.

The frame 1 of the tool comprises two similar spaced side plates 2 and 3 having their forward ends spaced by a cross bar 4 permanently riveted to the side plates and the rear ends permanently fastened by rivets to the upper end of the stationary handle 5. This.

' handle extends downwardly ata slight angle and is substantially U-shaped in horizontal cross section and has the upper end cut away to provide opposing horizontal guides 6 and stop shoulders 7 at the ends of the guides. In

. advance of the handleythe plates are provided .Fig. 3 is'an enlarged detailed verticalsec-' with opposing lugs'8 which carry a. cross pin later described.

I At the end remote from the handle the plates are supplied with a pair ofopposing vertical slots 9 and 10 above which are out curving flange like extensions 11 and 12 which serve to reinforce theplates at such points.

At the upper. ends of the slots, I locate two outstanding guide wings 13 and 14 against which the teeth of the saw to be sharpened rest.

A substantially rectangular top plate 15is Y mounted slidably between the side plates and has the forward end thereof curved downwardly and centrally vertically slotted as indicated at 16. Inwardly from the plate, I

locate a square bar 17 of predetermined length; the bar being spaced from the plate'by a spacing strip 18 and being fastened to the plate by a rivet 19 passing through the bar,

a the spacing strip and the plate. 7 The bar is considerably shorter thanthe plate although it is longer-than the spacing strip. The top plate, bar and spacing strip being permanently fastened together, form' what I term a shifting member slidably mounted in the frame. I I

The rear end of the top plate rests slidably on the guides 6 whilst the forward end is slidably carried by a cross pin 20 extending between the plates 1 and 2 and passing between the top plate and the bar 17 directly'in advance of the spacing strip 18. The rivet 19 also fastens a flat spring 21 to the shiftable member and therear end of the spring is exi tended beyond the'rear end of the bar and is provided with an eye 22 to which I attach a coiled spring 28 which has; the rear end thereofpassed through a suitable opening 24 provided in the handle 5 and fastened from withdrawal by an exterior vertical pin 25. This spring 23 acts to pull the shiftable member rearwardly and its rear positionis limited by the engagement of the rear end of the plate .15 withthe shoulders 7. l u

A movable handle 26 also substantially U-shaped in horizontal cross section is provided and the upper end of the handle terminates in opposing lugs 27 which are received within the frame and span the rear endof the working eond-i'tions will be iniadvance of the bar 17 to which they are pivotally connected by a cross pin 28. The latter handle is also pivotally connected to the frame by a cross pin 29 carried bythe lugs 8. From the above arrangement, it will be obvious that one can advance the shifting member bygrasping the hand lc ls 'betiween :the fingers and. thumbnnd 7 closing" the 'mov%le="handle"towardsthe stationary one.
